Analysis of advantages and disadvantages of three lead-acid batteries

The body battery is also a lead-acid battery system, and the gel battery is only a colloidal substance added to the electrolyte.

The anti-vulcanization ability and low-temperature performance of the colloidal battery are better than ordinary lead-acid batteries.

However, the production process of colloidal batteries is higher than that of ordinary lead-acid batteries, and it is more prone to thermal runaway.

Advantages and disadvantages of wound battery

Lamination:

1: size is more flexible, can be made into triangle, circle, etc.

2: mechanization is not easy to implement.

3: a block of crossroads, cross section is more, easily pierced diaphragm, easy to short circuit, easy generation pay reaction.

4: tension is not easy to control of the battery.

5: pole piece for inspection or pick easily.

Winding:

1: mechanization is easy, fast, homogeneity is more assured, is conducive to mass production.

2: there are positive and side tension is inconsistent, results in uneven internal response.

3: high coating requirements for pole piece.

4: request sheet layer has certain elasticity, otherwise in the bend easily fall off or broken.

5: as the electrode a lead from the plate, the distribution of electric field problems. Electrode layer has good electrical conductivity.(turn) is the key technology is difficult to control.

Most commonly used start metal battery life expectancy are three years or so, more than this time performance will decline, if the vehicle at low temperature start difficult phenomenon appeared, the proposal for replacement in advance. But battery products on the market at present all sort is more, exactly which may be a lot of people don't know better. Today I will simply introduce the current battery for you what are the types, and their respective advantages and disadvantages.

Low ordinary lead-acid batteries

Ordinary lead-acid batteries

Truck on the most commonly used start metal storage battery is the ordinary lead-acid battery. It possesses the advantages of cheap, low temperature discharge current. But because of its internal working medium is water and solution of sulfuric acid in the use of water will be difficult to avoid evaporation and electrolysis, so we need to add distilled water on a regular basis to ensure that the liquid surface height.

Add battery supplements

It is precisely because of the characteristics that need to be maintained that the battery is often used for scrapping damage due to improper maintenance, because not everyone will properly maintain it. For example, distilled water should be added when the electrolyte level is lowered, but some people may mistakenly add battery stock to it, causing excessive sulfuric acid concentration, or adding mineral water or inferior distilled water to the battery, which will cause the battery to be short. Damage is scrapped within the time.

Lead-acid battery internal plate

In addition, the performance of the plate of the ordinary lead-acid battery is poor to withstand vibration. In use, the active material on the plate will continuously fall off with the bump vibration, and the effective reaction area of the plate is continuously reduced. When the detached active material accumulates to a certain height at the bottom of the battery, it will cause a short circuit of the plate, causing serious self-discharge, resulting in the battery being scrapped.

Scrap battery

Finally, ordinary lead-acid batteries cannot be stored for a long time after the electrolyte is added, and must be loaded. Because the battery has self-discharge phenomenon, when the power is insufficient for a long time, the battery plate will undergo irreversible vulcanization, which will eventually result in scrapping.

Low maintenance free lead-acid battery

Maintenance-free lead-acid battery was upgraded version of ordinary lead-acid battery, it has a fully enclosed shell structure, use need not be maintained, eliminating the common battery needs to add distilled water trouble, often is a more easy to use product.

Maintenance free storage battery

In addition to the free maintenance, shock resistant ability of this kind of battery is also more outstanding than ordinary battery, but the price is relatively more expensive. Another of its whole life compared with the ordinary lead-acid battery was not significantly beyond, so the overall use of the cost would be a little higher than ordinary lead-acid batteries. Another legend, anecdotal and maintenance-free lead-acid battery discharge capacity at low temperature without ordinary lead-acid battery is strong, but the true is also is unable to determine.

Low winding type lead-acid battery

Winding type lead-acid battery may not have heard of many people, it is the biggest difference between and ordinary lead-acid battery structure, internal structure of a spiral winding type, and the common battery is flat plate structure. It has a big start power uniformity, long service life, charging fast, strong vibration and impact resistance, etc.55 degrees Celsius below zero to 75 degrees Celsius temperature within the scope of work, the other is its internal all solid structure, so the vibration resistance is very strong, can withstand the vibration of the four times stronger than ordinary battery.

Winding type lead-acid battery

Its internal structure is spiral, and the electrolyte is completely adsorbed by the battery separator, and there is no flowing liquid, so it can be used normally even in an inverted state. In addition, the wound battery can output three times more current than a normal battery, making it ideal for cold start in winter.

In addition, the self-discharge of the wound battery is very small, and it can even start the vehicle after being stored for one or two years after being fully charged. This is unmatched by ordinary batteries. Although the performance of the wound battery is impeccable, the price is too expensive. It is currently only used on some high-end passenger cars, and the truck usage is almost negligible. However, if you have special needs, you can also consider replacing the ordinary battery with a winding type, as long as you can accept its high price.

Summary

On the whole, what is most suitable for us is actually the old ordinary lead-acid battery, although it has its own shortcomings. However, today fake and inferior products are mixed with the market. It’s not easy to buy genuine products. Here, I suggest that you try to buy some well-known brand products from dealers with good reputation. It is relatively more reliable than roadside stalls.
